ps it's dead easy to boroscope now:ooh:
pps here one can see typical impulse/reaction turbine blades. . . .or rather lack of.:p :8 :p

Tested satis on ground please report further.;)

Minor Heat Damage - Inspect every 1000 hrs :)

Re: BA 747 Engine Fire
 

Well it certainly doesn't look like mechanical damage in this section. The problem affecting this section might have started further forward.

Does anybody know if this is the HP, IP or LP

At least one can see the results of leaving the fuel petcock on after the air pressure pretty much quits. Pretty typical of an engine cock-up during a high crew workload like a takeoff.

Aircraft now back at LHR.Engine changed a good job done by all concerned.

Re: BA 747 Engine Fire
 

Lets not forget British Airways annually carries more than 36 million air travellers on 360,000 flights safely.

Unexpected failures will always happen, and in this instance the tech crews actions and training saved the day.

Well done:)

Re: BA 747 Engine Fire
 

Would have loved to have seen that being done..........:ok:

Re: BA 747 Engine Fire
 

The HPT looks to be intact . . . . unless there's more missing at the bottom:ugh: what you can see there is the 3 stages (stubs:ooh: ) of the LPT and the single stage of IPT, forward of that is the HPT NGV's that in this half look ok except for the mechanical damage to the trailing edge.


coor! I've got a rep power of 7 whats that good or bad?:confused:

Re: BA 747 Engine Fire
 

Are these the same PW4000 that had 2 serious fire incidents in FCO in 2004?

Re: BA 747 Engine Fire
 

Looks like the company BBQ was a great success! Oi Nigel! I said rare, not well done!

Re: BA 747 Engine Fire
 

First engine jettison handles, now a fuel 'petcock' ?
Was I absent from groundschool the day these items were covered?? :confused:

???

Re: BA 747 Engine Fire
 

Petcock? The Dart had a sniffle valve! By the way a certain amount of wear on the trailing edge of the NGV's is acceptable in some engines.

Re: BA 747 Engine Fire
 

When you figure out whether a high rep number is good or bad tell me

I wondered if it was the number of time my posts had been reported to a moderator for violations :}

Back to the engine, thanks for explaining the stages, I think.

I agree the nozzle vanes at the front sure do look like inlet vanes coming out of the burner. But to me I can count three stages of stator stumps and three stages of tubine gas path seals (your expertise). Those inlet vanes are mostly damages at midspan and not much near the outer so in my mind that is thermal flame damage and not mechanical damage.

I'll be curious to what more gets said about this although it probably is of low interest to most folks.

Looks very much like a Pegasus I once 'borrowed' from HMQ and trashed:)
